This week’s drone strikes in North and South Waziristan ended a 36-day-long hiatus in the strike campaign in Pakistan’s tribal areas. The pause in strikes was the second longest since the US campaign was ramped up in the summer of 2008 under the Bush administration.

The longest pause was 55 days, from Nov. 26, 2011, to Jan. 10, 2012, when the Obama administration put the program on hold after US and Pakistani forces clashed in Mohmand. Pakistani troops had attacked US forces on the Afghan side of the border, and the ensuing firefight resulted in the deaths of 24 Pakistani soldiers. The US later apologized for the incident, despite having been attacked first by the Pakistani soldiers who failed to disengage after US aircraft signaled that US forces were involved.

Mir Ali is a terrorist haven

The Mir Ali area is in the sphere of influence of Abu Kasha al Iraqi, an al Qaeda leader who serves as a key link to the Taliban and supports al Qaeda’s external operations network. Taliban leader Hafiz Gul Bahadar and the Haqqani Network also operate in the Mir Ali area. Moreover, Mir Ali is a known hub for al Qaeda’s military and external operations councils.

Since Sept. 8, 2010, several Germans and Britons have been reported killed in Predator strikes in the Mir Ali area. The Europeans were members of the Islamic Jihad Group (IJG), an al Qaeda affiliate based in the vicinity of Mir Ali. The IJG members are believed to have been involved in an al Qaeda plot that targeted several major European cities and was modeled after the terror assault on the Indian city of Mumbai in 2008. The European plot was orchestrated by Ilyas Kashmiri, the al Qaeda leader who was killed in a US drone strike in June 2011.

Prior to this year, the US has been pounding targets in the Datta Khel, Miramshah, and Mir Ali areas of North Waziristan in an effort to kill members involved in the European plot. Al Qaeda and allied terror groups such as the Islamic Movement of Uzbekistan, the Islamic Jihad Group, the Eastern Turkistan Islamic Party, Jaish-e-Mohammed, Lashkar-e-Jhangvi, and a number of Pakistani and Central and South Asian terror groups host or share camps in the region. These groups are given aid and shelter by Taliban leader Hafiz Gul Bahadar and the Haqqani Network, a Taliban subgroup run by Siraj and Jalaluddin Haqqani.

Despite the known presence of al Qaeda and other foreign groups in North Waziristan, and requests by the US that action be taken against these groups, the Pakistani military has indicated that it has no plans to take on Hafiz Gul Bahadar or the Haqqani Network. Bahadar and the Haqqanis are considered “good Taliban” by the Pakistani military establishment as they do not carry out attacks inside Pakistan.

Background on the US strikes in Pakistan

Today’s strike is the 22nd in Pakistan since June 4, when the US killed Abu Yahya al Libi, one of al Qaeda’s top leaders, propagandists, and religious figures. Abu Yahya was killed in a strike on a compound in Mir Ali in North Waziristan. Uzbek, Tajik, and Turkmen fighters belonging to the Islamic Movement of Uzbekistan were reportedly among the 14 terrorists killed along with Abu Yahya.

The drone program was scaled back dramatically from the end of March to the beginning of the fourth week in May. Between March 30 and May 22, the US conducted only three drones strikes in Pakistan’s tribal areas as US officials attempted to renegotiate the reopening of NATO’s supply lines, which were closed from the end of November 2011 until July 3. Pakistan closed the supply lines following the Mohmand incident in November 2011.

In addition to Abu Yahya, three other high-value targets have been confirmed killed in the strikes in Pakistan this year. A Jan. 11 strike in Miramshah, the main town in North Waziristan, killed Aslam Awan, a deputy to the leader of al Qaeda’s external operations network.

And sometime earlier this year, a US drone strike killed Abu Usman Adil, the emir of the Islamic Movement of Uzbekistan. Adil succeeded Tahir Yuldashev, the co-founder of the IMU, who was killed in a drone strike in September 2009. Adil is credited with increasing the IMU’s profile in Pakistan and Afghanistan after the death of Yuldashev, US intelligence officials have told The Long War Journal. Whereas Yuldashev had been content with confining the group’s operations largely to Pakistan’s tribal areas, Adil pushed to expand operations in northern and eastern Afghanistan, as well as in the Central Asian republics.

Four senior jihadist leaders, including Abu Kasha al Iraqi and Fateh al Turki, are reported to have been killed in drone strikes in North Waziristan since the beginning of August, although their deaths have not been confirmed. Badruddin Haqqani, a top leader in the al Qaeda-linked Haqqani Network, is thought to have been killed in a drone strike in North Waziristan. Afghan Taliban spokesman Zabihullah Mujahid and a Haqqani Network spokesman denied reports that claimed Badruddin was killed, and said he “is in the country and he is occupied with his operational responsibilities.” Afghan, Pakistani, and US intelligence officials have said that Badruddin is dead.

And Emeti Yakuf, who is also known as Abdul Shakoor Turkistani, may have been killed in the Aug. 24 drone strike in North Waziristan’s Shawal Valley that hit a training camp. Yakuf directs al Qaeda operations in Pakistan’s tribal areas.

The program has been scaled down from its peak in 2010, when the US conducted 117 strikes, according to data collected by The Long War Journal. In 2011, the US carried out just 64 strikes in Pakistan’s border regions.

So far this year, the US has launched 43 strikes in Pakistan against al Qaeda and allied terror groups, just five more than the 38 strikes this year in Yemen against al Qaeda in the Arabian Peninsula. In 2011, the US launched 64 strikes in Pakistan, versus only 10 in Yemen.
